WITNESSES: fl /44W 1n, IBBrit lmown'that I, Jean C. LIGHTHOUSE,

vso

mount in the usua a "citizen. of the United States and resident of Rochester, int-he county of Monroe and Stateof New York,have invented certain new and useful Improvements in Wheels,

of which the following is a specification.

The ob'ect oft-his invention is to produce a wheel, aving a. resilient tire comprising a number of removable. and interehau ble sections, in which the sect-ions shall be rmly and securely'held-in place, but in which the sections may be rea 'ly and convementl releasedflwhen necessary for their remove To this end the invention consists in the wheel hereinafter described, as the same is defined in the succeeding claims.

In the accompanying drawings, which illustrate the preferred embodiment of my invention, Figure tie a side elevation, partly in section, of the complete wheel; Fig 1 2 is a section on the line 22 of Fig. 1 g. 3 is a longitudinal section of a port on of the rim and tire of the wheel; Fig. 4 1s a section on the line 4--4 of Fig. 3; Fig. 5 is a. per

infective view of one tire-section; and Fig. 6 ,isan enlar section on the line 6-6 of Fig, 1, looking from beneath.

The illustrated embodiment of my invention is provided with a hub and s okes of ordinarv form, and 11 ion the spo 'es 1 is manner, a wooden felly or rim 2.

The tire is made of a number of short sections, each of which is provided with blocks 3 of rubber or other resilient material. These blocks are not secured directly to the telly, but are fastened to tire-block holders 'consisting of plates 4 of sheet metal. Two blocks are used in each section and three holders, one holder bein between the two blocks and the other two iolders at the outer ends of the blocks, as shown in Fig. 5. Each tire section is held together by two studs or rivets 5 which pass through the tire blocks and the holders. and are upset at the ends as shown in dotted lines in Fig. 3.

the remaining tire sections. When the several plates on each side are in position, however, they form continuous annular slots on their inner surfaces which engage the T-heads of the tire-block holders on both slltles, and thereby secure the tire sections in The plates 7 and 7 are secured in place upon the wheel by means of bolts 12 assing through the plates and the wooden elly. To support the plates against lateral strains, they are also connected by bolts 16 passing through the plates on opposite sides of the wheel and nearer to the outer edges of the plates than the bolts 12.

While the construction above described secures the tire sections against removal, it does not operate to secure them with absolute rigidity, and therefore I provide additional means for securing the tire sections, such means being ada ted to prevent all looseness or rattle of tie tire sections. To this end the tire sections are all erforated longitudinally, as shown at 8 in ig. 5, and through the perforations I pass a ringshaped fastening member 9. The ends of the member 9 are threaded right and left, and engage a nut 10 seated. as shown in Fig. 1, in a recess formed in one of the tire sections. The nut is provided with a worm wheel 11 which is engaged by a worm 14 journaled in hearings in the plates 7 and 7. A stem 15 with a squared end pro'erts through the plate 7 to the. side of the w leel. where it may be engaged by a suitable tool to turn the worm. Through these mean-- the clamping member 9 may be tightened after the tire sections and the side plates have been put in place. thereby taking up all looseness between the tire sections and the plates.

What I claim is 1. A wheel. having a circumferentiallydivided wheel rim comprising removable. oppositely-placed plates that in position form a circumferential T-shn 'ied market: a series of tire block holders having heads fitting in said T-shaped socket: tire blocks attached to said holders: and means for fastening said plates to the wheel for retnining said tire block holders thereon.

2. A wheel. having a rircumfcrcmiallv- (livided wheel rim comprising roumvahlc. oppositely-placed plates that in position form a circumferential T-shaped socket: tire block holders having heads fitting in a i i 969,68!

said socket, and each consistin of metallic tire block holders having heads fitting in lates formin sockets for one r more tire said socket; tire blocks attached to said locks; tire b ocks fastened in said holders; holders; and an annular fastenin piece and means for fastening said lates to the passing through said tire block 1101 ers and 5 rim for retaining said tire b ock holders adapted to be contracted to hold the same 15 th ere0n. together and to the rim.

3. A wheel, having a circumferential] JOHN C. LlGI-ITHOUSE. divided wheel rim comprising removab e, Witnesses: oppositely-placed plates that in position D.G-u1m1-m,

10 form a circumferential T-shaped socket; C. W.'CARROLL.
